Those cute tiny pigs cost between £150 and £700. They only weigh 250 grams at birth and are just the size of a tea cup.2 years later when they are fully grown, they weigh around 20-25 kg (50-60lb) and stand at around 35 cm (14in) tall. Even less for some…They can live up to 18 years and contrary to what we may think, they are very intelligent, low maintenance, quiet, very clean, have very few health issues and are easy to toilet. And last thing, “you can't get allergies from pigs as their skin is very similar to ours, and they have hair not fur.”In fact, they are the perfect pet!
